Backlight device and liquid crystal display apparatus

摘要

Disclosed is a light transmitting liquid crystal display apparatus used with advantage with a television receiver having a large-sized display not less than 30 inch. A backlight section ( 3 ) sending out illuminating light is formed by a plural number of rows made up of many light emitting units ( 15 ) arranged on the back surface of a liquid crystal display panel ( 8 ). Each light emitting unit includes many LED units ( 18 ) mounted on an interconnection substrate ( 17 ) and is mounted in this state on a heat dissipating plate ( 28 ). A reflecting section ( 6 ) for reflecting the light radiated from each LED is formed by a large number of reflective sheet pieces ( 27 ), assembled from one heat emitting unit to another, and a reflective plate ( 26 ) secured to reflecting plate supports ( 40 ) formed on the heat dissipating plate.
